I was called on embarkation day to ask if I was on board or not, I almost answered to hang on while I checked with the people in the cabin next door, but thought better of it. Apparently I had not visited the muster station, I asked if my wife had checked in at the muster station and was told yes she had, I did wonder how she had managed to check in when I hadn't, and I was pushing her wheelchair?
Computer systems are fine just as long as they are not reliant on idiots to input the data.
